Clinical T
This input is used for staging
Notes
**Note 1:** Assign 88 for in situ cases (behavior code /2). TNM nor FIGO include an in situ category for sarcomas of the corpus. **Note 2:** When both the Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and extension information on the primary tumor are available, use the extension information to assign the T in preference to a statement of FIGO stage - see Registrar notes. * If the only information is FIGO III [NOS] or IIIC, assign the appropriate stage and leave clinical T, N, and M blank. If the only information is FIGO stage IVB, leave T and N blank and see M **Note 3:** Extension to the bowel or bladder mucosa must be proven by biopsy in order to rule out bullous edema.NAACCR Item

c0 | cT0 | Not defined by UICC** | No evidence of primary tumor |
c1 | cT1 | Tumor limited to the uterus | Note: T1 has subcategories of T1a, T1b and T1c. Assign T1 only when there is no information available to assign one of the subcategories. Invasive cancer confined to corpus uteri Invasion of myometrium, NOS WITH or WITHOUT involvement of endocervix Tunica serosa of the visceral peritoneum (serosa covering the corpus) Cervix uteri, NOS, but not beyond uterus Localized, NOS FIGO Stage I [NOS] Stated as T1 [NOS] |

c2 | cT2 | Tumor extends beyond the uterus, within the pelvis | Note: T2 has subcategories of T2a and T2b. Assign T2 only when there is no information available to assign one of the subcategories. FIGO Stage II [NOS] Stated as T2 [NOS] |
c2A | cT2a | Tumor involves adnexa | Adnexal involvement, NOS Extension or metastasis within true pelvis: Adnexa Fallopian tube(s) Ligaments: Broad Round Uterosacral Ovary(ies) Parametrium Visceral peritoneum of pelvic organs excluding serosa of corpus uteri FIGO Stage IIA Stated as T2a |
c2B | cT2b | Tumor involves other pelvic tissues | Extension or metastasis to: Cul de sac (rectouterine pouch) Pelvic wall(s) Parietal serosa of pelvic cavity Ureter Vagina Vulva Described clinically as "frozen pelvis", NOS FIGO Stage IIB Stated as T2b |
c3 | cT3 | Tumor involves abdominal tissues | Note: T3 has subcategories of T3a and T3b. Assign T3 only when there is no information available to assign one of the subcategories. Abdominal tissues involvement, NOS Further contiguous extension Stated as T3 [NOS] |
c3A | cT3a | One site | Infiltration of abdominal tissues, one of the following sites: Abdominal serosa (visceral or parietal peritoneum of abdomen) Sigmoid colon Small intestine Other abdominal structures FIGO Stage IIIA Stated as T3a |

c4 | cT4 | Tumor invades bladder or rectal mucosa | Invasion of: Bladder wall Bladder, NOS excluding mucosa Rectal wall Rectum, NOS excluding mucosa Extension to bowel mucosa or bladder (excluding bullous edema) FIGO Stage IVA Stated as T4 |
88 | 88 | Not applicable | In situ case but no pTis is defined by TNM Death certificate only (DCO) case |
